# TJ SIS Math Problem 2019

TJHSST admissions exam question, aka SIS, adaptation of SIS Math Problem 2019.

Here is a reconstruction of the 2019 SIS Math question based on discussions with students and my own internet research.

The Chesapeake Bay holds about 18 trillion gallons of water. The Bay covers about 4,480 square miles or 2,867,200 acres. For working the problem I rounded up to three (3) million.

Each acre can hold 750,000 oysters. Each oyster can filter 50 gallons of water every day. Can there be enough oysters to filter the whole Chesapeake Bay in one day?
